Hi,

EternalMan mentioned that Clock Tree Insertion is done after the STA tool reads and analyses the post-layout netlist....and this would be called Clock Synthesis?

Okay, so what you're saying is that STA would identify and instruct the layout tool to place buffers at clock branches to clock inputs...?

Thanks.
 

hi,
STA tool just analysis you timing. but dont do any cts.
you have to use PC, Astro, or other p&r tools to do it. and of course if you want to specify clock buffers you want to use , you have to specify them in p&r tools. NOT STA!!!
